Description
Overview
8mm high-voltage power connector available in 2-pin (2P) and 3-pin (3P) versions, designed for new energy vehicles, lithium battery packs and energy storage systems. It carries high current through 8mm bolt-type contacts and includes an HVIL (High Voltage Interlock Loop) signal circuit for safe live disconnection.
Specifications
- Contact size: 8mm
- Rated voltage: up to DC 1500V
- Current rating by cable size:
- 25mm² cable → 125A
- 35mm² cable → 150A
- 50mm² cable → 200A
- Poles: 2P or 3P
- Termination: bolted lug terminals
- Housing: orange flame-retardant plastic with lever lock
- Sealing: silicone gasket (blue) for the panel-mount version
- Safety circuit: HVIL interlock loop (yellow / black signal wire)
Purpose
These connectors join heavy-gauge battery cables where the current is far beyond what ordinary connectors can handle. The lever lock keeps the connection mechanically secure under vibration, and the HVIL loop tells the system controller whether the connector is fully seated, so the system can cut power before the contacts are separated.
Applications
- New energy electric vehicles and electric buses
- Lithium battery packs and battery swap systems
- Energy storage systems (ESS) and UPS banks
- Construction machinery and industrial high-power equipment
- High-power charging equipment
How to Use
- Confirm the correct pole count (2P or 3P) and cable cross-section for your current requirement.
- Strip the cable to the length required by the lug, then crimp the lug onto the conductor.
- Bolt the lug onto the 8mm contact stud and tighten to the torque specified by your battery or vehicle manufacturer.
- Slide the contact assembly into the housing until it seats.
- Make sure the silicone gasket is correctly in place before closing the housing on panel-mount versions.
- Close the lever lock until it latches — the connector is not fully mated until the lever clicks home.
- Connect the HVIL signal wire to the interlock circuit so the controller can detect the connection state.
- Never disconnect under load. Isolate the circuit first.
